Title: Improved hogshead loader and compactor
IPC: B65B1/24
Filed: 1955-05-20
Abstract: 769,987. Filling containers. GAY-BELL CORPORATION. May 20, 1955 [June 10, 1954], No. 14692/55. Class 94(1). A mechanism for loading hogsheads 28 with tobacco comprises an extension 27 for fitting on the hogshead mouth, a charging shell 23 and a continuously rotating cone 24, both carried by a vertically reciprocating beam 22, the cone and shell being lowered at intervals to compact the charge. Tobacco is supplied by a conveyer 26 to a distributing saddle 50, which may be continuously agitated, and drops onto the cone 24 driven by a motor 44 clamped to a non- rotating shaft 33. The shaft 33 is slideable in the beam 22 and when the cone and shell 23 are lowered, the shell lower edge descends to the level of the cone bottom, once the latter has contacted the charge, before both move downwards together. When they rise, this process is reversed so that any tobacco packed between the cone and shell is permitted to fall out. Means are provided to reduce the headroom needed for the mechanism. As shown, slots 58 in the sides of the extension 27, permit the beam 22 to descend below the extension's upper edge. The slots are normally closed by transparent panels 59, 60 which are telescoped downwards against springs 64, 67 by the beam. In another embodiment, Figs. 7-9 (not shown), the extension is supported from the beam by cables attached to spring take-up mechanism the cables being attached to the uppermost of telescoping panels covering slots in the extension. In a further embodiment, Figs. 10-16 (not shown), the charging shell and two rings forming the extension are arranged to telescope as the beam descends, the lowermost ring being supported from the beam by cables attached to a counterweight. The cone is vertically agitated.

Patent GB-382901-A (GB)
Title: A process for the treatment of precious metal-containing materials
IPC: C22B3/08
Filed: 1932-05-24
Abstract: Material containing precious metals for example gold, silver, and platinum, as well as non-precious metals, such as the material obtained on fusing together alloys rich in copper and gold, such as old gold, silver articles, old gold-plated articles, and silver-plated articles, &c., is subjected to a preliminary mechanical-chemical treatment whereby the precious and non-precious metals are separated and may be subsequently extracted.  The mechanical-chemical treatment consists in converting the material after melting into a porous granular or finely divided condition and subjecting the material in this condition to an oxidizing and calcining treatment, thereafter leaching out the oxidized material with dilute sulphuric acid, and finally separating the solution containing the non-precious metals from the undissolved residue containing the precious metals.  A jet of water or compressed air, to which if necessary additional quantities of oxygen have been added, may be applied to the molten material to convert it into the granular form.  For the oxidizing treatment, which is effected with the application of heat, solid, liquid or gaseous oxidizing agents may be employed; for example air, supplemented if desired by additional quantities of oxygen, is blown into the material.  To facilitate the action of the oxygen, loosening agents for example sulphur, or metal sulphides, may be added to the material.  The loosening process may take place before or during the oxidizing treatment.  Copper passes into solution as sulphate and may be recovered therefrom. The residue, preferably after centrifuging is either cast into anodes and subjected to a process for recovering the precious metals, or is fused with scorifying or dissolving agents into a material suitable for cupelling.  If the original material contains only silver and is free from other precious metals the residue may be directly refined with suitable oxidizing agents or electrolytically refined by known methods.

Abstract: 698,868. Differential switches. METROPOLITAN RAILCARS (GANZ PATENT), Ltd., and LEHEL, V. Dec. 18, 1950 (Sept. 24, 1949], No. 15027/49. Class 38 (v) [Also in Groups XIX and XXIV] A balk device responsive to changes in the relative speed of two rotating shafts, e.g. 5, 6, Fig. 1, comprises two or more friction clutches which release balk members in successive stages as predetermined speed ratios obtain between the shafts, permitting stepwise movement of a control number 3, which movement may merely indicate when a predetermined speed-ratio condition exists ; may be used as a safety speed governor where the shaft 5 is driven by a synchronous motor, or as part of a switch gear controlling paralleled alternators; or to control engagement of gears or dog-clutches in a vehicle change-speed gear. Fig. 1, which is explanatory only, has a single balk member 1 with limited circumferential freedom on splines 20, Fig. 3, associated with a gear wheel 8, driven by the shaft 6, and comprising one element of a cone or multi-plate friction clutch, the complementary element of which is a bevel 9 geared to the shaft 5. Relative rotation in the direction of the arrow 14 turns the balk-member 1 to one limit position, in which the apertures 23 therein are out of register with axial keys 21 on the control member 3 which latter is thereby prevented from axial movement, and pressure thereon engages the friction clutch. Relative rotation in the opposite sense turns the balk-member 1 to its other limit position in which its apertures 23 permit axial passage of the keys 21, thus allowing movement of the control member 3. The multi-stage balk devices are described only in relation to controlling engagement of gears and dog-clutches in a vehicle charge-speed gear (see Group XXIV).

Title: Radio direction finding systems
IPC: G01S1/02
Filed: 1938-05-20
Abstract: 499,712. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd. May 20, 1938, No. 15106. Convention date, June 11, 1937. [Class 40 (v)] In a directive aerial system, particularly an overlapping beam transmitting system, disturbances due to reflections of the radiation from reflecting objects are eliminated by radiating from the aerial an auxiliary radiation directed towards the reflecting object. The Figure shows an overlapping beam system keyed in dot-dash rhythm in which the radiation characteristic from the source S is oscillated about a directive axis XY and in which reflection from the obstacle AB obscures the true axis XY by causing false axes within the area ABRT. This effect is eliminated by radiating from the source S an auxiliary equi-signal line or pseudo-axis towards the obstacle AB. Thus a continuous signal is reflected from AB, which is superimposed on the normal dot-dash signals in the area ABRT, but which does not produce false axes in this area. The true axes XY and the pseudo-axis are produced by causing the alternate dot-dash radiation characteristics to assume the shapes SICJKFSLMS and SHCDEFSGS respectively, and the pseudoaxis is arranged to be in the direction of the obstacle AB by causing the secondary lobe SLM of the "dot" characteristic to be tangential to the alternate "dash" characteristic at the obstacle AB. Any ambiguity caused by the pseudo-axis may be eliminated by emitting a further radiation modulated in a characteristic manner in the direction of the obstacle AB.
